WebInbreeding is the mating of individuals related by ancestry. It is measured as the probability that two alleles at a locus are identical by descent (F). Inbreeding increases homozygosity … Inbreeding depression is the reduced biological fitness which has the potential to result from inbreeding (the breeding of related individuals). Biological fitness refers to an organism's ability to survive and perpetuate its genetic material. Inbreeding depression is often the result of a population bottleneck.
